Description

This disclosure relates to refrigerators. Patent Document 1 discloses a refrigerator. This refrigerator uses a multi-flow type refrigeration cooler having a flattened tube with multiple refrigerant flow channels to perform heat exchange in the refrigeration cycle. Japanese Patent Publication No. 2018-048799 A schematic side cross-sectional view of the refrigerator in Embodiment 1.A schematic front view showing the refrigerator in Embodiment 1.Refrigeration cycle diagram showing the refrigeration cycle of Embodiment 1Perspective view showing the refrigerator cooler of Embodiment 1Plan view showing the refrigerator cooler of Embodiment 1Front view showing the refrigeration cooler of Embodiment 1Side cross-sectional view showing the area around the suction port of Embodiment 1 (Knowledge and other information that formed the basis of this disclosure) At the time the inventors conceived this disclosure, a refrigerator had been disclosed that used a multi-flow type refrigerator cooler having a flattened tube with multiple refrigerant flow channels formed inside to perform heat exchange in the refrigeration cycle. This refrigerator was equipped with a refrigerator cooler in the refrigerator cooling chamber, and the refrigerator chamber was cooled by cooling the air with the refrigerator cooler. However, the inventors discovered that with conventional technology, when air flows into the refrigerator cooler, some of the air remains stagnant in the refrigerator cooler chamber, making it difficult for air to flow into a part of the refrigerator cooler, thus reducing cooling efficiency. To solve this problem, the inventors have come to form the subject of this disclosure. Therefore, this disclosure provides a refrigerator that can improve cooling efficiency. The embodiments will be described in detail below with reference to the drawings. However, unnecessary details may be omitted. For example, detailed explanations of already well-known matters or redundant explanations of substantially identical configurations may be omitted. This is to avoid the following explanation becoming unnecessarily verbose and to facilitate understanding for those skilled in the art. The attached drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter described in the claims. (Embodiment 1) Embodiment 1 will be described below with reference to Figures 1 to 7. [1-1. Structure] [1-1-1. Refrigerator Configuration] Figure 1 is a schematic cross-sectional view showing the refrigerator according to the present invention. As shown in Figure 1, the refrigerator 1 has a box-shaped body 10. At two locations in the vertical direction of the body 10, an upper partition plate 11 and a lower partition plate 12 are provided, dividing the inside of the body 10 into three spaces. The space above the upper partition plate 11 is designated as the refrigerator compartment 13, the space between the upper partition plate 11 and the lower partition plate 12 is designated as the freezer compartment 14, and the space below the lower partition plate 12 is designated as the vegetable compartment 15. A low-temperature compartment 16, which is said to be at a lower temperature than the refrigerator compartment 13, is provided at the bottom of the refrigerator compartment 13. A shelf 17 for placing food is provided inside the refrigerator compartment 13. Inside the freezer compartment 14, there is an ice-making compartment 18 for storing ice. A side-opening refrigerator door 20 is provided on the front of the refrigerator compartment 13, allowing it to be opened and closed. A freezer compartment drawer door 21 is provided on the front of the freezer compartment 14 so as to be able to be opened and closed, and a freezer drawer case 22 for storing food is provided on the inside of the freezer compartment drawer door 21. A vegetable compartment drawer door 23 is provided at the front opening of the vegetable compartment 15 so as to be able to be opened and closed, and a vegetable compartment drawer case 24 for storing food is provided inside the vegetable compartment drawer door 23. As shown in Figures 1 and 2, a refrigerating cooling chamber 30 is provided on the rear side of the refrigerator compartment 13 of the refrigerator 1. A refrigerator compartment duct 31, which extends above the refrigerator compartment 13, is connected to the refrigerating cooling chamber 30. The refrigerator compartment 13 and the refrigerating cooling chamber 30 are separated by a partition wall 85 that extends vertically. The refrigerated cooling chamber 30 houses a refrigerated cooler 32. The refrigerated cooler 32 is a microchannel type cooler. A microchannel type cooler is, for example, a cooler composed of a flat, porous tube and fins. A flat, porous tube is a flat tube with multiple channels formed inside through which the refrigerant flows. Further details of the refrig
